Alkenes from Alcohols by Tandem Hydrogen Transfer and Condensation

A ruthenium‐catalysed oxidation of alcohols by hydrogen transfer has been coupled with organocatalysed condensations using pyrrolidine or piperidine, to give α,β‐unsaturated esters and nitroalkenes. Reactions proceed with high (E)‐selectivity and provide an efficient and straightforward route to α,β‐unsaturated compounds.
